And yet organizations like Marzano are racking in millions of dollars on a failed system.

I think the natural critique would be to extend the metaphor. Data enthusiastic school reformers would say if only 39% of passengers made it to the desired location we would want to reform pilot training as well.

Yet with outcomes the metaphor breakdown. Take medicine. Success is clearly defined. You get better or you die. Results in education just are not as binary.

In the spirit of full disclosure I to make some money working in the field of teacher evaluation (about a million short of my first million), but I have no problem profiting from either my passions or problems I want to help solve.

Are there evaluation programs that improve practice. I believe so. I have seen systematic approaches to evaluation that increase the instructional capacities of schools. The successes have more to to do with people than data points.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
